Summary

The work will involve building new features, improving existing functionality, working with frontend and backend code, and integrating APIs as the product grows. Our core stack includes Next.js, React, TypeScript, Node.js, REST APIs, and database-driven functionality. Experience working with existing SaaS products and understanding an established codebase before making changes is important. We’re looking for someone who communicates clearly, writes maintainable code, and can take ownership of features from implementation through testing. Please include 1–2 SaaS or full-stack projects you've personally worked on and briefly explain what you built.
